That’s definitely a factor. That and the automatic reduction in carb intake with such a caloric restriction. I mean, if they fed them pure sugar, they’d still be getting “only” 200g of carbs per day which is still less than what a lot of people who developed diabetes used to eat. More realistically they are likely getting significantly less carbs per day with elements of fasting thrown in.
